<dt><em>Description</em>:</dt>
<dd><p><code>CTIME</code> converts a system time value, such as returned by
<a href="TIME8.html#TIME8">TIME8</a>, to a string. The output will be of the form &lsquo;<samp>Sat

<p>This intrinsic is provided in both subroutine and function forms; however,
only one form can be used in any given program unit.
